From the function structure diagram that shown above, there is two sources that used to running our products which is the electrical energy from battery and the human energy for manual control. For the electricity, the energy is then converted to the kinetic energy which battery supplies voltage to the motor, controller and also for the blade. After the motor running and the blade is rotating, the lawn can be functioned and use to mow the grass. For the human power source, this source is separated into two sub-function which one is manual push the lawn mower for the purpose to run the blade and other one is control remotely by giving the signal to the controller.Â
